Transcript of Scuba Dive

By Dalton Cone, Haley Davis, and Wayne Hancock! Scuba Dive! The Task We are supposed to figure out how much air is needed for a 30 minute scuba diving trip. To find the volume of air you would need to breathe while being underwater for 30 min. We calculated the amount of breaths normally taken while exercising for 5 min and multiplied the number by 6. To measure the amount of air per breath we exhaled into a balloon. The air from the balloon was then measured in milliliters with a syringe. The Procedure DATA!! The tank will be under pressure of 21.124atm. Extra Questions! 5. If the temperature is high or low, the volume and pressure would increase or decrease at the same rate. You would need less gas in Florida than in Maine because the water temperature is warmer thus causing pressure and volume to increase. 4. 6. 7.The pressure under water would be so great that the tank would implode under the pressure. The pressurization allows the tank to withstand the intense pressure of the depths. 8.It might explode because the pressure and volume would increase due to the higher temperatures. 9.First the oxygen masks would drop for the passengers. Then the pilot would need to quickly descend to at least 10,000 ft since the amt of O2 avail for passengers would be difficult to determine. Airplanes today are manufactured to withstand depressurization, however the plane could explode if it had any defects in its construction.
